To (cZZ whom it may concern Be it known that 1, ROBERT WILLIAM SIL- vnnsinns, tormerly residing at 100 Grange Terrace, Wood street, Norton, Malton, in the county of York, England, but now of l l St. Panls Terrace, Norton, Malton, in the county of York, England, have invented new and useful Improvements in or Relat ing to Rug and Carpet Making Machines, of which the following is a specification.

l his invention relates to improvements in rug and carpet making machines of the type in which strips or tabs of cloth are fed to, and passed through, a canvas or other woven sheeting which forms the back or foundation of the rug or carpet, and in which tabs or strips of cloth are secured; and it particularly refers to that class of machine in which a number of needles are mounted upon a horizontal bar to which a vertical intermittent reciprocating motion is imparted by means of cams and levers from some rotating part of the machine.

The object of this invention is to produce a machine of high etliciency as regards the work performed in a given time, and which consists in providing means for drawing a number of strips or tabs of cloth simultaneously through a double fold of the canvas or other woven sheet or backing, the said canvas being clamped on to the perforated or recessed wings or arms of an intermittently rotating roller, the strips or tabs of cloth having been previously placed on an inclined board from which they are pressed on to the pins of a traveling lag or sheet mounted upon endless chains by which they are conveyed to a number of springs or clips mounted upon the inner ends of a number of slotted bars or levers connected together in a lazy-tong arrangement so as to bring the clips or tabs of cloth into position to be seized and held by the needles which are also arranged to form aws for drawing the tabs or strips through the double folds of the canvas backing.

This invention consists in the details of construction and combination of the parts hereinafter described and claimed.

In the drawings hereunto annexed 1 have shown a method for carrying the invention into effect, in which- Figure 1 is a part side elevation of the machine with the needles open in the lowest position and with the clips or springs in position for receiving the strips or tabs of cloth from the pins of the traveling lag sheet; Fig. 2. is a plan looking at the top of Fig. 1; Fig. 3. is a part section on line A, A, Fig. 2; Fig. l. is a side elevation of the portion of the machine shown at Fig. l with the needles open at the upper portion of their stroke, and the springs or clips in po sition for delivering the strips or tabs of cloth to the needles; Fig. 5. is a part side ele vation of the framework of the machine, and of the inclined board upon which the strips or tabs of cloth are arranged for placing them on the traveling lag sheet; Fig. 6. is an end elevation of Fig. 5; Fig. 7 is a plan of same; Fig. 8. is a part sectional elevation of the inclined board shown at Fig. 5 with the tab pressing device in an open position; Fig. 9. is a part sectional elevation of the inclined board shown at Fig. 5 with the tab pressing device closed, and with a strip or tab of cloth pressed on to the needles of the traveling lag sheet; Fig. 10. is a part elevation of the mechanism for opening and closing the tab pressing device; Fig. 11. is a plan of same; Fig. 12. is a part elevation of a portion of the machine showing the needles in their open and closed positions together with the canvas clamping device closed. and means for clearing the tabs from the path of the needles; Fig. 13. is a part elevation of winged roller and of the clamping device open; Fig. 14. is an elevation of a needle closed; Fig. 15. is an end elevation of the same; Fig. 16. is an end ele vation drawn at the opposite side of Fig. 14-; Fig. 17. is a diagrammatic view showing the position of the cam and levers for opening the needle when the latter is at the top of its stroke; Fig. 18. is a diagrammatic view showing the mechanism for rotating the winged roller; Fig. 19, is a diagrammatic view showing the lever mechanism for operating the clearing rod; Fig. 20. is a diagrammatic view showing the cam and levers for raising and lowering the needle bar; Fig. 21. is an elevation of the cam for raising and lowering the needles; Fig. 22. is a sectional elevation of the same on line B, B, Fig. 21; Fig. 23. is an elevation of the cam for operating the winged roller, the clamping jaws, and the tab clearing bar; Fig. 24. is a sectional elevation of the same on line C, C, Fig. 23; Fig. is a sectional elevation of the lags with pins attached thereto;

Like parts in all the views are marked with similar letters of reference.

The framework of the machine comprises the standards a, a slotted at (Z, bed I), stays 0, 0, 0, and a pair of standards f mounted upon the bed 6. In the slots d a bar 6 is made to intermittently reciprocate, and a spindle 9 upon which are mounted sprocket wheels h is made to intermittently rotate in the bearings of the standards f. In some cases the standards 7 may be arranged to form a part of the framework of the machine, but for convenience in construction and adjustment they are shown mounted separately upon the bed of the machine. Bearings are also provided for the various shafts to be here inafter described in the standards a.

z is the driving shaft of the machine upon which are mounted the fly wheel j, cams 7c and Z, eccentric m and crank n.

The machine may be driven either manually, as illustrated, by means of the lever and the handle 79' mounted on the shaft 2, or by any suitable power means substituted inilieu thereof.

. The slotted portion (Z of each standard (1 forms a vertical slide in which is arranged to work a flange or other block (7 adapted to receive the ends of the needle bar 0. The needle bar 6 is. made for the greater part of its length rectangular in cross section and provided with enlarged ends,- which are circular in cross section,and the outer ends of the needle bar are reduced in diameter so as to pass into, and be secured in the blocks 9.

An intermittent reciprocating motion is imparted-to the needle bar e,-a's shown at Figs. 3 and 20,by means of the cam Z through bowl or runnerv 1",whieh works in the cam path Z ,carried by a pin on the pendant lever s mounted upon the rocking shaft 255 To the rocking shaft t are also fixed a-pair of levers u arranged respectively at suitable distances from the end of the rocking shaft. The inner ends of the levers u are jointed to levers 41 mounted upon the reduced ends of the needle bar. As the driving shaft 2' rotates the cam Z causes the needle bar to be raised and lowered asthe bowl or runner works in the path Z of the cam. To the upper surface of the needle bar 6 are fixed at suitable distances apart a number of vertical bifurcated supports w to which the needles are jointed. The vertical supports for the needles are arranged at suitable distance apart to cor respond with the center of the distance between each of the strips or tabs of cloth m which are inserted, as shown at Fig. :27, in the canvas backing y. The tabs of cloth x are inserted in rows in said backlng.

Each needle consists of two portions .2 and e ,-as shown at Figs. 1, 3, 1 1 to 17,- which are pivoted at Z to the supports w in a similar manner to a pair of scissors. The portion 2 of each needle is longer than the portion 2 and the longer or projecting part is made to form a point for piercing through the canvas or other backing y. The lower part of each of the portions 2 and 2 of each needle is curved outward, as shown at 2 and 3 of Figs. 14 and 17. The lower curved end portions of each needle are connected together by rods 4: and 5. The rods 1 and 5 extend across the machine between the standards a, and are provided on each of their outer ends with bowls or runners 6, 7, 8 and 9 which work against the vertical cam paths 10, and 11, as shown at Figs. 1, 3, 12 and 13, which are employed for opening the needles when they are at the lowest portion of their stroke. It will readily be understood that a pair of cam paths 10 and 11 are provided upon each standard a. lVhen the runners 6, 7, S and 9 pass off the cam paths 10 and 11 the neodles are closed by means of the spring 12, the ends of which are connected to the lower parts of the curved portions 2 and 3. When the needles have been raised by the cam and levers as hereinbefore mentioned and described,as at Fig. 20,they are opened by the lever mechanism shown in diagrammatic view at Fig. 17. That is to say, on the fly wheel is provided and fixed a cam 13 which engages with a runner 1 1 mounted upon a lever 15 fixed upon a shaft 16. On the shaft 16 are two or more levers 17 which are connected by link 18 to bell-crank lever 19', which is fulcrumed at 20 to the pendant portion or bracket 21, fixed to, or carried by, needle bar a. To the lower arm of the bellcrank lever 19 is jointed a link 22, the upper end of which is connected to an arm of an inverted bell-crank lever 23; the other arm of the bellcrank lever 23 is connected by link 24 to the rod 4 which passes through the curved portions 2 of the needle. The curved portions 3 of the needle are connected. to the upper end of the arm of curved lever 19 by means of link 25, the opposite end of which is connected to rod By this means it will readily be seen that when the cam 13 operates bowl or runner 14: and the lever mechanism connected therewith. the two portions 2 and s of the needle will be operated for opening the needle as shown at Fig. 17. The two rods 4 and 5 are connected together by a number of springs 28 (Fig. 17) which are employed for closing the needle as soon as the roller passes off the cam 13.

Although only one set of levers and links 17 to are shown it will readily be understood that additional sets may be employed as circumstances require.

Above the slots 0? which form a vertical slide is mounted in suitable bearings on the standards a a roller provided with, say, four, arms or wings, or webs 27 to which an intermittent rotary motion is imparted by lever and paw]. mechanism as shown in the diagrammatic view at Fig. 18, actuated by cam 73 (n igs. 13 and 23) through runner 29 mounted on lever 30 fixed to shaft 31. 3 On the shaft 31 is fixed a lever 32 (Fig. 18), the outer end of which is connected by rod 33, to the short arm of bell-crank lever 3 1. The last named bell-crank lever is mounted upon a shaft 35, and this long and curved arm is connected to the slotted lever 36, the lower end. of which is jointed to the bellcrank lever 37 which is fulcrumed upon the spindle or trunnion 38 of the winged roller. On one or both ends of the spindle or trunnion 33 is provided a ratchet wheel 39 and a disk 40 In the ratchet wheel are provided a number, say, four, of teeth 11 with which the pawl 42 is made to engage. The pawl is jointed to the outer end of lever 37 and it is kept to its work by means of spring 43. In the disk 40 are formed a number, say, four, of recesses aid with which a stop pin 15 is made to engage. The stop pin is mounted upon a double ended lever or shoe 116 which is fulcrumed at 47 to a bracket 4-3 (Fig. 1). The sole or plate of the shoe 46 is acted upon when it is desired to withdraw the pin from a recess 14 by the short arm 4-9 of the double ended lever 37; a spring 50 is attached to the shorter end of the shoe 16 for :eeping the pin -15 within the recess when not acted upon by the short arm of the bell-crank lever 37. The canvas y is made to pass over three of the four wings 27 as shown at Fig. 12, and when in this position two of the wings will be in a vertical position and two in a horizontal position and the canvas is closed upon one of the horizontal wings 27 by means of the jaws 51 and (Figs. 12 and 13). The jaws 51 and 52 consist of a pair of plates which are fixed respectively to a number, say, four, of levers and 541 which are fulcrumed upon the rod The levers 53 are shown at Fig. 13 in the form of a bell-crank lever, and each lever 53 and 54: is connected respectively by a rod 55, 56 to a pair of levers 57 and 58 arranged one behind the other fixed to the shaft 31 which is operated by cam 70. The wings 27 and the aws 51 and 52 are perforated or recessed at suitable distances apart to permit of the passage of the needles through the canvas and for the canvas to be readily traversed along as occasion requires. The canvas in its passage to the wings 27 passes over a roller 0 which may be mounted upon stay a and from thence it passes,-as shown at Fig. 3,to the wings 27 and after receiving a tab or strip of cloth it is conveyed to a number of rollers 59 and 60 mounted in a of the board 63.

tit

frame 61 which is carried at its upper end by the stay 0 The rollers 59 and 60 may be of the same or different diameters. In the drawings roller 59 is shown larger than the rollers 60 and it is provided with a recess 62 which is slightly narrower than the width of the canvas backing y in order to enable the inserted tabs to pass readily over it.

The tabs 0: which form the pile of the rug or carpet, are of any predetermined length, width and color, and are cut to size and arranged upon an inclined board 63 (Figs. 5 to 11). The tabs or clips of cloth w are arranged in position upon the board 63, which is divided into a number of compartments by vertical projections 64 which only extend for a short distance from the front edge 65 The projections 6d are arranged at such a distance or pitch apart that the tabs can be readily passed between them. Between each vertical projection 61- is also formed a recess 66 for the passage of the pins on the lags to be hereinafter described. The tabs to be employed in the rug or carpet making are arranged on the face of the inclined board 63 and are retained thereon by the projecting battens 67. The board or table 63 is retained in position both as regards the standards a and the angle of incliation by the brackets 68 which are fixed to the hereinbefore described standards 7 which carry the spindle g and sprocket wheel h.

To the front edge 65 of the table or board 63 is ointed a second angular board 69 which forms a stop for the tabs. On the inne-r face of the angular stop 69 are formed a number of grooves or recesses for the pins of the lags. The recesses or grooves 70 are at the same pitch as, and corresponding in position with, the grooves 66.

An intermittent tilting motion is imparted to the angular stop board 69 by means of a pair of levers 71 and 7 connected together by a hand bar or red 73. The levers 71 and 72 are fulcrumed upon pins 74- carried by the guide pieces 75 and pendant brackets 7 The inner end of levers 71 and 72 are ointed to the spindle 77 which carries the sprocket wheels 7 8 and 7 9, around which the endless chains 80 are arranged to pass. The spindle 77 is arranged to work in the slots 81 of the brackets 76, and the spindle is connected by bifurcated levers S2 with levers 83 fulcrumed at 841 to the pendant brackets 7 6. The free end of each lever 83 is connected by a second bifurcated lever 85 and pin 86 to the outer end of the angular stop board 69. The angular stop board is pivoted at 87 to brackets 88 fixed to the inclined board of table 63. As the spindle 77 is raised by the downward movement of the levers 71, 72 an upwardmovement is imparted to levers 83 and .85 for turning the inner end of the angular stop board 69 from the position shown at Fig. 8 into that shown at Figs. 9 and 10.

&

When the angular stop board is turned into the position shown at Figs. 9 and 10 it will press a tab on on to the pins 89, mounted on the top of the lags 90, which are fixed at suitable distances apart upon the endless traveling chains 80. hen the levers 71, 7 2 are in the raised position shown at Fig. 5, that is, with the spindle 77 at the bottom of the slots 81, then the sprocket wheels 7 8, 79 will have been withdrawn to their lowest position for enablingthe tabs to pass down and through the recesses 66 so as to be conveyed into the position to be received by the spring clips 91 formed on the ends of levers 92. i

The lags 90 are shaped in cross section as shown at Fig. 25 so that their reduced upper portion and the pins 89 thereon will pass into each spring clip. The spring clips 91 are shaped as shown at Figs. 3 and 1 and are made to fit the upper reduced portion of the lags 90. A part of the spring. clip is cut away so as to permit of the pins 89 passing through and clear of the spring clip.

The strips or tabs of cloth or when received from the inclined board of table 63 are in a fiat condition, as shown in dotted lines at Figs. 3 and 1, and after the spring clips 91 have passed on to them, as shown at Fig. 3, they assume the curved or U-shaped form shown in dotted lines at Fig. 25. The spring clips 91 are made of such a strength as to hold aptab or strip of cloth in its curved or ,U-shaped position and withdraw it fromthe pins 89 and to carry it into the position shown at Fig. 1 so that its end may be received andpassed between the scissor like jaw portions of the needles. The spring clips are attached-to the upper ends of a number of levers 92 which are mounted upon a rod orspindle 93 carried by two or-more levers 91 which are fulcrumed to the standards oat 95; Each lever 92 is bifurcated at 96 at its inner and lower ends, and the said levers are connected together at or about their centers, and also at their bifurcated ends respectively by means of the slotted plates 97, 98. The levers 92 are also jointed or connected to a lazy-tong arrangement of levers 99, as shown at Fig. 2. In order to open and close the lazy-tong arrangement of levers 99 their opposite ends are connected to the projections 100, 101, and the bosses 102,103 which slide upon the rod or spindle 93.

In the periphery of the bosses 102, 103 is formed an annular groove or recess 10 1, 105, in which the bifurcated or hooked end of levers 100, 107 are made to work for expanding or contracting the lazy-tong arrange- 'ment of levers 99 for regulating the position of the spring clips with regard to the lags 90 and. pins .89, and also with the pointed needles which simultaneously pass through the-double layer of canvas when it is clamped upon a wing, or web 27 The levers 106, 107

1,135.,eos

are fulcrumed to the cross bar 108 which is fixed at its respective ends to the levers 9 -1 so as to move therewith.

On the inner and curved ends of the levers 106, 107 is respectively mounted a bowl or runner 1,09, 110. The bowls or runners 109, 110 are arranged to work within the inverted trough shaped cam paths 111, 112 which are fixed to the bed plate I) of the machine at or about the angle shown at Fig. 2. These cam paths are made in the form shown and have slots or openings in their upper sides through each of which one of the levers 106, 10?, passes, the bowls or runners on the inner ends of said levers working against the inner surface of the ca m paths.

The required intermittent oscillating movement. for moving the levers 91 and 92 and spring clips 91 into the position shown at Figs. 3 and 4: is imparted by means of the eccentric m mounted upon the driving shaft 73. The strap m of the eccentric is connected to a curved bifurcated lever 113, the upper end of which is attached to a lever 111 which is fixed to the rod or spindle 95 upon, which the levers 91 are mounted. As the eccentric revolves, and when at or about its upper stroke, it will have caused the levers to have traveled from the posi tion shown at Fig. 3 to that shown at Fig. 1. Sinniltaneously with this movement of the levers 91- the lazy-tong arrangement of levers are closed from the open position shown at Fig. 2 into a position for delivering the tabs or strips of cloth w to the jaws of the vertical reciprocating needles, which will then have passed through a double layer of the canvas, and have been opened as shown at; Fig. 1. Simultaneously with this motion for actuating the levers 9 1 the levers 92 are caused to turn on the rod 93 for reversing their position by means of the lower ends of the lazy-tong arrangement of levers 99 having a central fixing 115 and secured thereto, to which is jointed the curved rod 116. The opposite end of the curved rod is provided with a bifurcated end 117 to which is jointed a curved lever 118 provided with bifurcated ends; the upper bifurcated end of lever 118 is connected to a lever 119 mounted loosely upon spindle 31, owing to the movement for turning over the said levers being quicker than the movement required for oscillating the levers 91. The lower bifurcated end of the curved lever 118 is connected to the pin or bolt 120 which attaches the bifurcated end 113 and lever 111 together. During the movement of the levers 91 from the position shown at Fig. 3 to the closed position shown at Fig. 41 the lovers 106, 107 pivotally carried by said levers 91 are rocked on their fulcrums by the cam paths 111, 112, and their outer ends caused to approach each other, thus partly collapsing the lazy-tong arrangement of levers 99 and moving spring clips 91 on the levers 92 closer together and in line with the vertically reciprocating needles 2, a.

An intermittent rotary motion is imparted to the sprocket wheel h from the crank it mounted upon the driving shaft 2'. The crank is connected by rod 121 to a bell-crank lever 122 fulcrumed to a bracket 123 fixed to one of the standards a. One arm of the bell-crank lever 122 is connected by a rod with a second bell-crank lever 124 which is also bifurcated so as to permit of a ratchet wheel 125 and stop wheel 126 working between it. The bifurcated bell-crank lever 124 is mounted loosely upon spindle 9 while the ratchet wheel 125 and stop wheel 126 are keyed or otherwise fixed on the same spindle as the sprocket wheel h. To the bellcrank lever 124 is also jointed between its bifurcations a pawl 127 which engages with the ratchet wheel 125 when it is required to intermittently rotate the sprocket wheel h. The pawl 127 is retained to its work b spring 128. Below the stop wheel 126 is fulcrumed a lever 129 in the form of a shoe and to this lever is fixed a stop pin 130 which enters a recess 131 of the stop wheel for retaining the sprocket wheel and lag 90 in position. for the removal of the tab or strip of cloth 00 by a spring clip 91. The stop pin 130 is moved out of position by the short arm of the bifurcated lever 124 coming in contact with the sole plate 132 of lever 129. The stop pin 130 is retained in position Within a recess 131 by means of a coiled spring 133, one end of which is attached as at Fig. 3 to the lever 129, and the opposite end to the standard f.

After the tabs :12 have been inserted in the canvas or other woven backing 3 in rows, as shown at Fig. 27 the tabs require,after the needles have descended to their lowest position,to be moved out of position so that the needles on their next upward stroke will not come in contact with the tabs in the previously inserted rows. To accomplish this a rail or rod 134 is mounted in a pair of double ended levers 135 (Figs. 3 and 19) fulcrumed on a rod 136, one end of which is fixed to the standard a; and at the other end to a bracket 137 which is fixed to the sec ond standard. The bracket 137, shown in dotted lines at Fig. 19, is provided in order to permit of the movement of the slotted lever 36. The upper portions of the curved levers 1.35 are connected together by a second rod or bar 138 and a connection is made between the rod 138 and a bell-crank lever 139,mounted upon shaft or spindle 35, by a rod or bar 140. The shorter arm of bell-crank lever 139 is connected to a lever 141 mounted upon shaft or spindle 31 by a rod or bar 142. The requisite motion is imparted to rod or spindle 31 from cam as previously explained. When the needles are passing through the double layer of canvas clamped on to one of the wings 27 the clearing rod 134 will be in the position shown at F i g. 12, but when the jaws 51, 52 are opened to their widest position, as shown at Fig. 13, and the spring clips 91 and levers 92 being about midway between the positions shown at Figs. 3 and 4, and also in or about a vertical position prior to being turned over for delivering the tab to the needles, then the clearing rod 134 will be in the position shown at Fig. 13.

The action of the apparatus is as follows :The tabs or strips of cloth m, which form the pile of the rug or the carpet, are first placed upon the table 63 and arranged by the operator into the spaces between the vertical projections 64 at the front and lower edge of the table or board 63. After the operator has arranged by hand the tabs or strips of cloth :1? as just described, the hand rail 73 is depressed in the direction of arrow shown at Fig. 5, for raising the sprocketwheel 78, 79 and lags 90,which are fixed. to the endless chains 80,and pins 89 so that they will pass into the recess 66 in the board or table 63. Simultanoeusly with the raising of the sprocket wheel 78, 79, the angular stop 69 is turned over into the position shown at Figs. 9 and 10 for pressing the tabs or strips of cloth w on to the pins 89. After this has been done the sprocket wheel 7 8, 7 9 is returned to the original position shown at Fig. 5. A rotary motion is imparted to the driving shaft 71 either by hand or power and the spring clips 91 having been moved into the position shown at Fig. 3 receive the tabs and withdraw them from the pins when the lags 90 have been caused to travel from the front of the bar into the position shown at Fig. 3. The required intermittent motion for causing the endless chains 80 to travel is imparted by the ratchet mechanism previously described.

The levers 92 with a tab in each of the spring clips 91 are then caused to travel by the means previously described into the position shown at Fig. 4, during which movement of the levers 92 and 94 the position of the spring clips will first have imparted to them the oscillating movement for closing the clips closer together so as to be of the same pitch as the vertical reciprocating needles, and they are also turned over so as to deliver the tabs or strips :0 to the scissor like aws of the said needles. hen the spring clips 91 are in the position shown at Fig. 3, for receiving the strips or tabs 03 from the lags 90, the vertical reciprocating needles will then be at the bottom of their stroke with their jaws open,as shown at Fig. 3,and the clamping jaws 51, 52 open, as shown at Fig. 13. During the movement of the spring clips 91 from the position shown at Fig. 3 to that shown at Fig. 4 the I tabs are left in that position by the needles.

needle bar is raised and the runners 6, 7, 8 and 9 will then pass in their upward position out of contact with the cam paths 10, 11 for closing the jaws of the needle. Simultaneously with this upward movement of the needles the jaws 51, 52 will have been closed upon the canvas with one of the wings 27 between two layers of canvas so that by the continued upward movement of the needles with their jaws closed they pass through the perforations or recesses in both the aws 51, 52 and of the wing 27 and also through the two layers of the backing y. As soon as the needles reach the highest point of their upward stroke they are again opened,by the means previously described,-in order to receive the tabs or strips of cloth 00 which form the pile of the rug or carpet. On the descent of the needles the said tabs or strips are drawn through the two layers of the backing and when the said tabs or strips have been drawn about half their length the needles are again caused to open by the said runners coming in contact with the cam paths 10, 11, and the During the descent of the needles the spring clips are again moved into their outward position, and during such movement the clearance bar 134 is moved into the position shown at Fig. 3 for removing the row of tabs w just inserted in the backing y clear of the needles when they are again caused to ascend and. the jaws 51, 52 are then again opened and the wings 27 rotated so as to bring another wing into position, the perforations or recesses in the jaws 51, 52 and wings 27 permitting of the free movement and clearance of the inserted tabs 00. The outer end of the backing 3/ may be weighted for drawing it over the rollers 59, (30, and .when the backing is thus drawn forward the two free ends of each tab 00 will be on the same and underside of the backing and hung down in the position shown at Fig. 3. The backing 3 being held by a weight or other means is caused to travel forward with each intermittent rotation of the wings 27 The fold of the backing over the wing will, by means of thesame weight, be straightened or drawn smooth and the tabs, each drawn by a needle through perforations in the fold will'assume a looped position shown in Fig. 3, the reverse side of the backing or canvas when the rug is finished presenting the appearance illustrated in Fig. 27.

The cycle of operations for conveying the tabs to the needles and inserting them in the backing may be repeated until a rug or carpet of the required size has been made.

It will readily beundersteod that thenumber of intermittent vertical reciprocating needles and spring clips will be varied inaccordance with the width or number of tabs to be. inserted. In the drawings at Fig. 2

nine needles are shown by way of example only, but I wish it to be distinctly understood that their number may be increased as circumstances require. Also that the nu1nber of partitions and width of the board will require to be correspondingly varied.
